Abstract
The utility model relates to a vehicle universal joint transmission device, in particular to a drive shaft assembly which can be conveniently and rapidly disassembled. The drive shaft assembly comprises a middle shaft, a fixed-end universal joint which is arranged at one end of the middle shaft, and a sliding-end universal joint which is arranged at the other end of the middle shaft. The drive shaft assembly is characterized in that the middle shaft is divided into a left half shaft and a right half shaft; the left half shaft and the right half shaft are connected through a coupler which can be disassembled. Because the middle shaft is divided into the left half shaft and the right half shaft, when the fixed-end universal joint is damaged, the half shaft of the fixed-end universal joint and the universal joint can be conveniently disassembled for replacement; thus the structure overcomes the inconvenience and diseconomy in the long term as a result of the requirement for the operation of the whole vehicle or the disassembly of the whole drive shaft assembly, when the fixed-end universal joint is replaced; and the structure greatly improves the time efficiency and reduces the time cost.

Embodiment
Now in conjunction with the accompanying drawings the utility model is further described:
As shown in Figure 1 and Figure 2, but the embodiment of the drive shaft assembly of a kind of conveniently fast disassembling of the utility model, include jack shaft 2, be arranged on the fixed end universal joint 1 and the slippage end universal joint 3 that is arranged on jack shaft 2 the other ends of jack shaft 2 one ends, described jack shaft 2 is divided into left and right half 21,22, removably connects by joiner 23 between the left and right half 21,22.By jack shaft 2 being divided into the left and right half 21,22 that removably connects, thereby when fixed end universal joint 1 damages, can dismantle the semiaxis 21 and the universal joint 1 that are connected and fixed end universal joint 1 easily changes, changed people's need under car load, change the fixed end universal joint or whole drive shaft assembly disassembled and change inconvenience that the fixed end universal joint brought and uneconomical more all the time, greatly improved time efficiency and reduced time cost.
Joiner can have various structures, such as the n type joiner that adopts opening, when being set in a left side, during the two ends of right axle shaft, tighten up with screw at opening end and to realize the purpose that removably connects, what but present embodiment adopted is: joiner 23 includes a left side, right tie-plate 231,232, wherein, left side tie-plate 231 is fixedlyed connected with left half axle 21, right tie-plate 232 is fixedlyed connected with right axle shaft 22, a left side, right tie-plate 231,232 by screw 233 connections, in the diagram, described screw 233 is that eight circumference uniform distributions are on a left side, right tie-plate 231, connect a left side on 232, right land 231,232.Adopt the mode of present embodiment, it is reliable that the applicant thinks that it connects, and operation is also convenient, but the utility model is not got rid of the joiner that adopts other structure.
In the diagram, described left tie-plate 231 is provided with spline 2311, and the corresponding spline 211 that is provided with on the end of left half axle 21, and be provided with draw-in groove near the place, exterior edge faces at spline 211, spline 211 are set in the spline 2311 and with jump rings 234 location of end; Also be provided with spline 2321 on the described right tie-plate 232, the corresponding spline 221 that is provided with on the end of right axle shaft 22, and be provided with draw-in groove near the place, exterior edge faces at spline 221, spline housing 221 are located in the spline 2321 and with jump rings 24 location of end.Tie-plate and semiaxis pass through splined; its coupling reliability is good; it is also convenient to install; but such as the mode that adopts the square shaft square hole to add to lock screw (as the tie-plate upper aperture; the end of semiaxis is set as square shaft is set in the square hole, and then realize locking perpendicular to axis one lock screw being set on the tie-plate) or other connecting mode also still all within the utility model protection domain.
